| True measurement of speaker systems actual impedance at 1kHz |
| Three test ranges allow testing of home theatre and commercial sound systems |
| Measures transformer impedances |
| Battery operation |
| Low battery indication |
| Data hold function |
| 0 Ohm adjustment |
| EN 61010-1 CAT III 200V, EN 61326-1, EN 61326-2-1, EN 61326-2-2 |
|
| It is recommended a drawing be first made of speaker system to verify proper installation |
| Take care to ensure that the system is not connected to the amplifier |
| Ensure the system under test is not live |
| Check batery, of sysmbol appears on the display, replace with new batteries |
| Short the tips of the leads, adjust the "0 Ohm ADJ", control to set the reading of zero |
| Connect test leads to speaker or speaker leads. Note : Speakers may be connected together either in series or parallel to achieve desired final impedance |
| Rotate the function switch to a suitable range then press the push button to test and take the reading |
